[0058] Specifically, in the process of the plate rack 21 transferring the undried glass plate 8 from the feed port 12 to the discharge port 13, the undried glass plate 8 first passes through the heating section 14 and then passes through the cooling section 15.

[0061] Specifically, the first fan 41 draws the gas in the first air inlet channel 142 into the first air supply channel 141. When the gas enters the first air supply channel 141 through the air outlet end of the first fan 41, the gas is heated to a preset temperature by the first heating element 42. The gas heated to the preset temperature flows into the drying channel 11, thereby achieving the technical effect of the first hot air component 4 blowing hot air into the drying channel 11.

Such an arrangement can extend the time for the page-turning glass tunnel furnace 100 to dry the glass plate 8 so that the ink on the glass plate 8 can be completely dried.

[0064] Reference Figure 7-10In some embodiments of the present application, along the second direction of the furnace body 1, the side wall of the inner shell 17 of the heating portion 14 has a first wall surface 171 and a second wall surface 172 that are opposite and spaced apart.

In some specific embodiments, the second heating element 43 can be connected and cooperated with the outer top wall of the inner shell 17, and in other specific embodiments, the second heating element 43 can be connected and cooperated with the inner circumferential wall of the outer shell 16.

[0065] In addition, a first connecting hole 161 is provided in the outer shell 16 of the heating part 14 , and the first connecting hole 161 is connected to the first air inlet channel 142 and the external environment. The first connecting hole 161 is provided with a first throttle valve 1611 for adjusting the gas flow in the first connecting hole 161 .

[0066] Specifically, when the page-turning glass tunnel furnace 100 starts working, the first throttle valve 1611 is fully opened, the first fan 41 draws gas from the external environment through the first connecting hole 161 and transports it to the drying channel 11, and the first fan 41 simultaneously draws gas from the drying channel 11 through the air outlet 1721, the second heating element 43 heats the gas in the first air inlet channel 142, and the first heating element 42 heats the gas in the first air supply channel 141, thereby achieving the technical effect of quickly raising the temperature in the furnace body 1 to a preset temperature.

[0067] Furthermore, in the process of gradually increasing the temperature in the furnace body 1 to the preset temperature, the first throttle valve 1611 is gradually closed, thereby controlling the amount of gas sucked from the external environment by the first fan 41, and preventing the normal temperature gas in the external environment from entering the first air inlet channel 142. The normal temperature gas in the external environment is prevented from mixing with the gas in the first air inlet channel 142 to lower the gas temperature in the first air inlet channel 142, thereby reducing the time required to increase the temperature in the furnace body 1 to the preset temperature.

[0068] Furthermore, when the temperature inside the furnace body 1 rises to a preset temperature, the first throttle valve 1611 is completely closed, the first fan 41 draws gas from the drying channel 11 into the first air inlet channel 142, the second heating element 43 heats the gas in the first air inlet channel 142, and then the first fan 41 re-transports the gas in the first air inlet channel 142 to the drying channel 11, thereby realizing gas circulation in the furnace body 1. The first heating element 42 and the second heating element 43 do not need to heat the gas in the external environment, which can reduce the energy consumption of the first heating element 42 and the second heating element 43, and thus can reduce the energy consumption of the flip-type glass tunnel furnace 100.

[0069] Furthermore, when the temperature inside the furnace body 1 is higher than the preset temperature, the staff can also adjust the amount of gas in the external environment entering the first air inlet channel 142 through the first throttle valve 1611 to adjust the gas temperature of the gas blown into the furnace body 1 by the first fan 41, thereby achieving the technical effect of adjusting the temperature inside the furnace body 1.

[0070] In some specific embodiments, the second heating element 43 may be a ceramic heating element, but the present application is not limited thereto. The second heating element 43 may also be an iron mesh woven with heating wires, etc.

The gas at the tail of the heating section 14 is reheated by the first heating element 42 and the second heating element 43 and re-transported to the drying channel 11 by the first fan 41, thereby achieving the technical effect of recycling the gas at the tail of the heating section 14 and reducing the energy consumption of the page-turning glass tunnel furnace 100.

[0074] Furthermore, the amount of gas sucked from the tail end of the heating section 14 by the first fan 41 can be adjusted through the second throttle valve 1621. The worker can control the opening degree of the second throttle valve 1621 according to the temperature inside the furnace body 1, thereby preventing the gas at the tail end of the heating section 14 from being sucked into the first air supply channel by the first fan 41 in large quantities, and thereby preventing the first heating element 42 and the second heating element 43 from failing to heat the gas at the tail end of the heating section 14 to a preset temperature, causing the temperature inside the furnace body 1 to be lower than the preset temperature, thereby achieving the technical effect of maintaining the temperature inside the furnace body 1 at a preset temperature.

When the gas in the external environment enters the drying channel 11 through the fourth connecting hole 164 and the fifth connecting hole 173, the gas passes through the cooling fin group 52 and exchanges heat with the cooling fin group 52. The cooling fin group 52 cools the gas to a preset temperature, and then the cooled gas enters the drying channel 11 to cool the glass plate 8, thereby achieving the technical effect of the cold air component 5 cooling the glass plate 8.
